DRAET-YOKE FOR RAILWAY-CAR DRAFT-RIGG-ING.

Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Draft-Yokes for Railway-Car Draft-Rigging, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in draft yokes for railway car draft rigging. The object of my invention is to provide a draft yoke having a preliminary compression resisting member. I accomplish this object by providing the rear end of a U-shaped draft yoke with a spring cage adapted to receive a spring, and a spring cap operating therein and in engagement with the spring or springs, and arranged to bear against the rear follower or a com-' pression resisting member within the yoke so that in the movements of the yoke through its connection with the draw bar a preliminary compression resisting movement may be afforded in connection with different types of draft gear, and may thus afford such movement in a draft rigging 1n which the draft gear does not within itself contain any preliminary compression resisting members.

In the accompanying drawings forming a part 'of this specification Figure 1 is a side elevation of a draft rigging embodying my invention. Fig. 2 is a plan view. Fig. 3-is a perspective view of the rear end of the draft yoke and the preliminary compression resisting member connected therewith partly cut away to show the interior mechanism of said member.

In the drawings 4, 4 represent draft sills or parts of the car frame to which the draft rigging is attached, 5 a draw bar, 6a tieplate, 7, 7 stop members provided with the front stop shoulders 8, 8, and rear stop shoulders 9, 9, 10 a U-shaped draft yoke suitably secured at its forward free ends to the draw bar 5 the connecting means illustrated in the drawings being the pin 11 passing through the yoke and draw bar. Between the upper limb l2 and the lower limb 13 of the draft yoke are the front and rear followers 14 and 15 respectively, the rear follower in the typi; of draft gear illustrated from the front face 32 I in the drawings being an .incegr'airm aite Specification of Letters Patent.

is provided with a spring'cagef18suitably secured therein, preferably by the outwardly ing recess 20, preferably rectangular in' shape, containing the springs 21, preferably coiled springs, two in number, and one nest- Theinner rear end 17 ofthedraft yoke ed within the other, the said springs being 5 seated at their rear-ends against the rear portion 22 of the spring cage, and at their.

forward end within the hollow portion 23 of the spring cap 24. The spring'cap 24 is preferably provided at either side withithe faces 25, 25 adapted to slidingly engage the sides of the recess 20 in the sprmg chamber, and is also provided with a forwardly o ning recess 26 which receives the head 2 of the bolt 28, the said bolt passing rearwardly through the rear end of the yoke, and being provided in the outer surface of the yoke;

with the nut 29.

Although I have described the member 28 as a bolt, yet it will be understoodthat the same might be a rivet or other connecting member headed at the ends and hence where I I em loy the term bolt throughout this speci cation and in the claim, I wish it understood as covering all such devices.

The recess 26 is of sufficient len h to perments, and prevent binding of the s rings;

within the spring chamber upon ateral movement of the yoke. The forward face 31 of the spring cap engages the follower 15, and in normal position of the parts of the draft rigging is extended forwardly of the spring chamber.

Any suitable draft gear or compression resisting member may be inserted within the yoke. On forward movement of the yoke the springs 21, which in preferable construction are of lesser ca acity than" the compression resisting mem er 16, are com-' ement of the pressed through the enga d 01 ower 15, an

spring cap against the upon full inward movement of the springll cap the comprexion memher intheusualway.
